Iscar 6004963 Carbide Cutoff Insert 4mm Neutral

Product Description

The ISCAR 6004963 is a solid carbide cutoff insert from the Tang-Grip series, designed for grooving and slitting operations on metalworking lathes and turning centers. It carries a CVD-applied TiCN/Al2O3/TiN multilayer coating, which provides thermal resistance and wear protection across a range of cutting conditions. The insert features a 4.00 mm cutting width, a 0.25 mm corner radius, and a neutral lead angle with neutral hand orientation. A 7-degree relief angle supports clean chip clearance. The IC5400 grade targets demanding interrupted and continuous cuts on stainless steel and carbon steel workpieces. Installation and replacement are handled by machinists and CNC setup technicians.

This insert is suited for slitting and cutoff work on stainless steel and carbon steel in both production and job-shop environments. The neutral hand designation makes it compatible with standard Tang-Grip toolholders without requiring left- or right-hand-specific setups. The C chipbreaker geometry promotes chip control at moderate to high feed rates, reducing the risk of chip entanglement on CNC turning equipment. It is packaged individually and sold in single-unit quantities, making it practical for spot replacement or trial use.

Key Features

• CVD multilayer TiCN/Al2O3/TiN coating provides heat and wear resistance for extended tool life
• 4.00 mm cutting width with a width tolerance of 0.05 mm for consistent groove dimensions
• 0.25 mm corner radius minimizes stress concentration at the groove floor
• Neutral lead angle and neutral hand orientation for versatile Tang-Grip holder compatibility
• 7-degree relief angle supports chip clearance and reduces rubbing
• C chipbreaker geometry aids chip control on stainless steel and carbon steel
• ISO 13399 compliant for integration with digital tool management systems

Compatibility

Designed for use in ISCAR Tang-Grip series cutoff and grooving toolholders. Primary workpiece materials are stainless steel (ISO material code M) and carbon steel (ISO material code P).

Installation Notes

This insert is seated and clamped by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before changing inserts. Inspect the Tang-Grip toolholder pocket and clamping screw for wear or debris before seating the new insert. Do not exceed the toolholder manufacturer's recommended depth-of-cut or feed rate for the IC5400 grade.
